A bicycle security mount which includes a base and a pair of spaced supporting arms extending outwardly from the base. Each supporting arm has a threaded aperture for receiving a bolt. A shield is mounted on each bolt. Each shield has a bore and a counterbore. The shank of the bolt extends freely through the bore and lies entirely within the counterbore of the shield. The tines of the front fork of a bicycle are positioned on the security mounts so that the tines straddle the supporting arms. Each tine is positioned between a supporting am and a shield. The bolt lies within the downwardly facing open ended slot of the tine so that the tine is clamped between the shield and the supporting arm. The clearance between the bolt and the inner surface of the counterbore is too small to receive a conventional socket wrench but large enough to receive a socket wrench which is specifically designed for the bicycle security mount. More specifically, the bicycle security mount includes a cap for each shield. Each cap includes a head portion which has a socket for receiving the shield and a connecting arm portion. Each connecting arm portion has a hole. When the caps are mounted on their respective shields, the ends of the connecting arm portions overlap and the holes in the connecting arms are axially aligned with one another and axially aligned with the hole in a bracket which extends between the supporting arms.
